Please keep the discussion on the mailing list so that everyone can contribute and benefit. Also this discussion probably should have stayed on the paraview users list so I'm cross-posting there.<div><div><br></div><div>
I'm not certain if the 64 bit-ness of the MPI lib matters. It's certainly safer to stick with a 32 bit version if you are compiling 32 bit code (and 64 bit for 64 bit libs), but it might not be required. Someone else on the list may clarify.</div>
<div><br></div><div>In any case, the CMake FindMPI module we have has a rich and sordid history behind it. It could just be buggy on your system. Try moving the cxx.lib to the MPI_EXTRA_LIBRARY variable. I suspect it will build for you then.</div>

Thanks David!<div><br></div><div>Before turning off PARAVIEW_USE_MPI, I still want to have a try.</div><div><br></div><div>I have installed MPICH2(64bit) on my machine. Is the 64bit version OK?

<div><br></div><div>There is a small problem that CMake automatically sets MPI_LIBRARY to be "C:\Program Files\MPICH2\lib\mpi.lib C:\Program Files\MPICH2\lib\cxx.lib". So I have to manually split it into two separate lines for some projects in the ParaView solution. Otherwise there will be several errors from those projects, called "cannot open file 'C:\Program Files\MPICH2\lib\mpi.lib C:\Program Files\MPICH2\lib\cxx.lib'."</div>
<div><br></div><div>Currently I am finding all the projects which needs such split by compiling the whole solution again and again.</div><div><div><div><br><div class="gmail_quote">On Fri, Jan 6, 2012 at 4:30 AM, David E DeMarle <span dir="ltr"><<a href="mailto:dave.demarle@kitware.com" target="_blank">dave.demarle@kitware.com</a>></span> wrote:<br>

<br></div><div>Alternatively you could install MPICH2 or OpenMPI for Windows and then rebuild. When you turn on PARAVIEW_USE_MPI the first time, CMake should find MPI in your path and and determine what the correct settings for MPI_INLCUDE, MPI_LIBRARY and MPI_EXTRA_LIBRARY accordingly. The VTK and ParaView dashboards have a few examples, but it appears the Kitware hosted machines (see <a href="http://www.cdash.org/CDash/viewNotes.php?buildid=1886001" target="_blank">http://www.cdash.org/CDash/viewNotes.php?buildid=1886001</a> for example) all use Microsoft's MPI.</div>

Hi everybody,<div><br></div><div>These days I was puzzled by different kinds of errors when I tried to build paraview from open source code.</div><div><br></div><div>My machine is AMD64 and my OS is Windows 7 64bits.

<br></div><div>I do not know what the 12 unresolved externals are.
